I’m a retired Unix admin. It was my job from the early '90s until the mid '10s. I’ve kept somewhat current ever since by running various machines at home. So far I’ve managed to avoid using Docker at home even though I have a decent understanding of how it works - I stopped being a sysadmin in the mid '10s, I still worked for a technology company and did plenty of “interesting” reading and training.
It seems that more and more stuff that I want to run at home is being delivered as Docker-first and I have to really go out of my way to find a non-Docker install.
I’m thinking it’s no longer a fad and I should invest some time getting comfortable with it?
I started using docker myself for stuff at home and I really liked it. You can create a setup that’s easy to reproduce or just download.
Easy to manage via docker CLI, one liner to run on startup unless stopped, tons of stuff made for docker becomes available. For non docker things you can always login to the container.
Tasks such as running, updating, stopping, listing active servers, finding out what ports are being used and automation are all easy imo.
You probably have something else you use for some/all of these tasks but docker makes all this available to non-sysadmin people and even has GUI for people who like clicking their mouse.
I think next time you find something that provides a docker compose file you should try it. :)
